Near its enter and each lever is pru- 'vizieel with a roller 2?. These rnllers are rril'epted to ride on a rail 28 in! a purtinn nf their travel, wherebv they are raised from the carrier-plates. The rail is iuclmed at 7 one end to permit the mller to easily ride up thereupon. The rude L26 serve to hold the came-overs olrtllu 1lutes,unrl they are pin is adapted to engage radial sluts H in a v yhirh carries a frame 14, presided with a seraised and lowered to release or clamp the covers by the action of the levers, rolls, and rail just described.

Secured to a plate 29, mounted on the 5 framework, isa can-cover receptacle formed of vertical arms 30. ed on the framework, so as to yield in an upward direction, by means of studs 31, on which the late can slide, and which studs are surrounded by coiled s'rings 32, hearing on the plate. The plate is held from contact with the framework by adjustable screwbolts 33, extending through theplate. Extending rearwardly on the frame behind the plate 29 are guide-rails 34 between which is adapted to ii and slide a feedlate 35, having, a curved front edge 36 con orming to the curve of the center of a feed-aperture 37 in the plate 29. Thespace between the plate 29 and framework is ust sufficient to permit a single can-cover to be fed down through the plate so that its edge will clear the plate when the red rocating feed-plate is carried forward.' en the cover is forced under the plate 29, the latter will yield against its springs to permit the thicker portion of the central part of the cover to be forced between the late and frame.

e slide-plate 35 has an arm 38 on its under surface, which arm is pivoted at its inner end to a connecting-bar 39, secured to a shaft 40, journaled in the frame, which is actuated by a lever 41, fixed to the shaft and having a .free'end extending across theath of movement ofa circular wheel or wk 42, eccentrically and loosely mounted on the gearwheel 3. The connecting-bar 39is provided with 'a return-sprin 43, which serves to carry back "the rod and ever to normal position afterthey have been operated by the eccentrio disk and lever. I

The can-cover is fed from the receptacle to a can'ier-plate by the reciprocating feed-plate under and against the pressure of a s ring- 5 finger 44, secured to the plate 29, so that the coverwill be held in the carrier-plate until eng ed by the clamp' -rod.

an the main fram d i s mounted the com osition-applying mechanism, consisting 0 a tank, feeding means, and controlling means. A ivoted right-angled arm 45 extends into the ine of movement of the clamping-rods. When a can-cover is ushed under a clamping-rod, the latter wil be raised a sufiicient -5 5 her ht to come in contact with the arm 45 an raise the same. The arm is provided with a rocking shaft 46, which carries a depending arm 47, having a hook 48 at its lower end'wluch is adapted to engage a pin 49, proj I tingirom an arm 50, secured to a controlling-valve box 51, which'is mounted'on a pipe 52, connected to the composition-holdmg tank 53 by a rocking joint at 54. The tank 53 also supports a bar 55, on which the lever-45 is pivoted. Within the box 51 ex- The plate 29 is mounta tends a lunger 56, on which the box is slidable. 'l his plunger is provided at its lower end with a needle-valve 57, ada )ted to 0 en andclose the lower open end of ti whenthe latter is vertically reciprocated. At its upper part the plunger is divided and the two'parts connected by a coupling-sleeve 59, through which passes set-screws 60 to permit of the vertical adjustment of the plunger and its valve, wherebythe extent of the o ening,

and consequently the amount of fee of the composition through the. box, may be set at any desired de ree. The'plunger has at its upper extremities a slot-and-pin connection 61 with a pin projecting from the bar 55, and a coiled spring is confined between the upper end of the sleeves 59 and a washer 62, whereby the plunger is permitted a slight yielding movement in order, to enable the covers to readily slip under the same. The plu er is jointed at 58 to permit of a slight yi e lding mo'vement thereof to accommodate the arcshaped movement of the box. The valveboxis normally held closed by the engagement of the pin on its su porting-arm with the hook 48 of the de en ing arm 47.

The valve-box 51 o the supporting-pipe 52 is provided with a projection or lug 63, with which is adapted to make contact a swingin arm 64, mounted on the end of the vertica shaft 40, so that when said shaft is returned by its spri the arm 64 will strike the lug 63 and raise tie rockin [box-supporting pipe until the pin 49 of the atter enga es the book 48, whereupon the valve-box wil be closed by its valve and the escape of the composition cut off. Connected to the bar 55 and to an arm 64, rising from the valve-box, is a coiled s 65, the action of which is to throw tl ie box downward when the latter is released from the hook.

The tank 53 is adapted to contain a suitable linin composition. This composition is kept w lmixed and in a fluid condition by means of a mixer consisting of fixed mixerblades 67 and a dasher 68, provided with similar blades.

To the tank is connected at the upper end a suitable valve-controlled air-inlet pipe 69, through which compressed air is adapted to be forced in order to force the composition from the tank through the outlet-pipe 52 to the controlling-valve box. A

Secured to the main frame and to the rail 28 is a sto -bar 70, extending above and across the line of travel of the carrier-plates I toward a discharge-chute 71. The lined covers strike against this bar and are guided thereby down into the chute 71, which leads to an endless conveyer 72, by which the covers are carried to a suitable drier to fix the composition.

The shaft of the mixing-tank dasher is provided near its u per end with a pulley 73, which is driven y a belt 74, running over A by the continued movement of the shaft 5,

=ger track the 'pin 8 of the Geneva stop-movevwith the disengagement of the star-wheel guide-pulleys and driven by a pulley 76 on a shaft 77, which is provided with a drive pulley 78, connected to any suitable source of power.

.The operation of the machine is as follows; Can-covers of any des'red number are placed in the vertical receptacle 30. When the sliding feedlunger 35 is withdrawn to its uttermost position, there will be just enough space between the plate 29 and the frame to permit the edge of a cover to pass throu h the circular aperture 37 down upon the ame; but the higher central ort-ion of the cover will prevent the same om slipping out of position until the feed-plate is forced forwardto engage and push the plate from under the receptacle. The machine then bein driven through the main shaft 2 the central shaft 6 will be rotated by its Geneva stop-movement connection with said main shaft, so as to rotate the carrier-frame and carry each carrierlate 17 successively around in line wifh the eedplnnger guide-track 34. As a carrierplate comes into register with the feed-plunment will pass out of engagement with the slot in the star-wheel 10, so as to cease actuation of the wheel and the curved recesses 12 of the latter will then be engaged by the curved periphery of the mutilated disk 7, so as to etc and hold said wheel, whereb the carrier-p ate will be held in register wit the feed-plunger track until a cover is fed forward to the carrier-plate. Simultaneously and pin and stoppage of the carrier-frame the eccentrically-mounted disk 42, carried around will engage and actuate the lever 41 of the shaft 40, so as to rotate the shaft and through the connecting-arms 39 and 3Scsrry forward the sliding feedlonger plate 35, the front curved edge 36 olhwhlch will engage the edge of the cover and force the cover forward under and ast the late 29 to and upon the can'ierate 17. e plate 29 will yield by reason of its s rings 32 to permit the greater, thickness oft e central portion of the cover to pass thereunder. As the cover is. carried out onto the carrierlate it will pass under and be rcssed uponh vthe guide spring-finget. e bent edge ol the cover Wlll fit into the groove 18 of the plate. The plun or will be returned to retract-ed position, y the spriu 43 and simultaneously will, be an: gage by the pin, and the carrier-frame will be revolved another step 'so as to presents new: carrier-plate to the eed-track. As the oerigi er-plate moves away from the track the roller 27 of the lever 25 runs ofi' the endcf rai 8 and permits the holding-rod 26% do seen i, u on the cover. The weightoiglhe, roe ed ever locks the cover securel" centore; position on the carrier-plate. e first cafl -r-plate is then moved forward to the while simultaneous Y a succeeding cnrrien plate is presented to the corer-feed track and another cover fed thereto. The holding-rod 26, hearing 'on the firsvnamed cover, will be raised by the thickness of the cover sulii ciently high to come in contact with the extending arm of the pivoted lever 45, and thus rock said lever on its pivot, whereby the hook 48 of the depending arm will be released from the pin 49, and the box 51 will thus be allowed to rock downward on the plunger 56, this movement being aided by the spring 65, connected to the arm 64, at-

inched to the valve-box, The movement of of the box will withdraw its opening from the needlevalvc 57 of the plunger and permit a certain quantity of composition, determined bv the adjustment of theset-serews, to escape t ough the opening and upon tihe extended end ortion of the plunger which may be rovi ed, if desired, with suitable means 0 applyingxsthe composition to the edge of the can. i the edge of thecover is brought into position under the plunger the roller 19 on the end of the shaft carrying the carrier plate comes in peripheral contact with the continuously-driven endless belt 20, and by its pressure against said belt itis rotated; and with it the carrier-plate and oancover, so that he latter is circularly wi ed -under the composition-app! in means. he roller 19 is in contact wit 1; e belt long enough to two complete rotations to the carrier-plate and its cover. 1

r The mixing mechanism may be continw onsly or intermittently driven to stir up the composition. The compressed air may be admitted to the tank w enever re uired to supplyrthe pressure necessary to orce the composition through the feed-pipe.

As the carrier-frame again takes up and ithereen be driven past the composition-applying mechanism, the latter would not operative, since the interposition of the cover between the rod 26 and the cerrie nplate is o necessary in order to raise the rod suflrciently make contact with the lever 45' The roller 27 then engages the inclined end of the rail 28 and rides upon said raiLso as'to lift the lever 25 and raise the rod 26 from the cover. When thecarrier-plate passes under the stop-guide bar 70, the cover will strike against the latter and be ushed off thereby into the cover-chute 71, om whence it will fall onto the endless conveyer 72, which can ries the cover to a heater and drier.
